I FLUID-REGULATOR:

T all whom it may concern:

Be it known that I, JOHN 131.. OsMnn,'a citizen of the United States, residing at Boone, Iowa, have invented certain new and useful Improvements in Fluid-Regulators, of which the following is a specification.

This invention relates to improvements in fluid regulators.

The main ob ects of this invention are:

First, to provide an improved regulator" mechanism adapted for use either as a pressure or vacuum regulator, a reducing valve, Or a pump governor. Second, to provide an "improved fluid regulator mechanism in 'whichthe valve and valve. cage can be readily removed for repair without removing the mechanism from the llne 1n whioh t is installed. Third, to provide an improved regulator mechanism in which the parts are simpleand economical toproduce and very easily assembled or disassembledshould occasion require. 9 I y I Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims. I .1 v

' A structure wh'ch is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which: I

Figure I is a detail side elevation of a structure embodying the features of my invention. Fig. II is a detail plan view of the structure, appearing in Fig. I. Fig. III is a detail vertical section on a line corresponding to line 3-8 ofFig. I. Fig. IV is a detail vertical section on a linecorrespond ing to line of Fig. II. Fig. V is a horizontal sectionv on a line corresponding to line 55 of Fig. III. I y

In the drawings, similar reference. characters refer to similar parts throughout the several views, and the sectional viewsare taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the dra-wmg, the valve casing or body 1 is provided with internally threaded nipples 2 into which the line pipes 3 and a are threaded. In the structure illustrated, the pipe 5 is the inlet, and the pipe 4, the discharge. It is obvious that the body Specification bf Letters Patent. Pat t ept; 1914 Application fiIedJanuaryZS, 1913. Seria1No;744,239. I I I might be provided with suitable coupling flanges inlieu of the coupling nipples 2 and such couplings are preferred in the larger sizes. The body in the structure illustrated,

is open at both ends and has a cylindrical borejadapted to receive the cylindrical valve cage 'e jhavingspaced valve seat holders 6 I therein adapted to receive the valve seats 7. The casingdieads 8 are removably secured by means of thescrews 9. I These removable heads v8 fit against the flat ends of the casing. The casing is provided with an annular passage 19 su'rroiuiding the cylindrical valve cage 5, thecage being provided I with opposed ports 11 communicating with this passage, the ports opening between the valves12. These valves are of the disk type I and beveled to coast with thevalve seats 7 mounted on the valve seat; holders 6. The valves 12 are m'ounted on a: valve stern l3 eonin' on toboth, theste n being ;,ar ranged through suitable packing; glands designated generally the, numerals 11d, 14.1. The U valves. are provided with a spacing; sleeve 15. The valves areretained bythelock nuts 16. To assist the stem in guiding thevalves,

the valves are provided with Wings 17 which lprqect through and are in sliding engagement with the valve seat holders 6; The valves are thus very effectively supported and guided, which is afeatureof on high pressures. g v =1 I The valve casing 11s provided Wlthfil pas.- sage 18 communicating with the pipe 4,

great advantagewhere the regulator is used jivhilethe heads are provided with passages 19 connectingthe passage 18 with the ends of. the cylindrical valve cage. The valves112 are slightly out ofbalanca-thatis, one is of asomewhat greater area than theother Sdthatthe pressure tends to open the same. Packing disks 2O arefittedwithinthe ends of the valve cage asillustrated,;to assist in forming a tight j oint for the heads.

.The regulating diaphragm chamber casing or body 21 is mounted on a bracket 22 on the side'of the body l by means ofthe screw 23. The diaphragm-25 is supported within thediaphragm chamber by clamping its edges between the sections forming the diaphragm chamber casing,see Fig. IV.;

,The lower section 26 .of the diaphra in a chamber casing is provided with a cylin er extension 27 in whichthe regulating spring 28 isarranged; This spring28 is arranged provided with to the stem 13 of the fluid valves. The lever hanger 33 carried 32 is fulcrumed on the by the bracket 22. Thepipe 34 connects the regulating ordiaphragm chamber with the fluid tank, radiator, or the like.

To adapt the structure to high pressures, a pipe-35 is connected to the diaphragm chamber below the diaphragm. This has the effect of reducing the area of the pressure on the diaphragm as the diaphragm is a plunger 36 which projects into the cylinder extension 27 of the diaphragm chamber, the plunger being provided with a suitable packing. The pipe 35 is provided with a valve 37 so that it may be cut oil when desired. This pipe 35 is connected to the pipe 34 or to the same source of fluid supply. The cylinder 27 is provided with a port 38 to permit the free escape of air from below the plunger. l/Vith the parts thus arranged, when the pressure in the diaphragm chamber falls below a predetermined point, the diaphragm is raised by means of the control spring 28, thus opening the valves. These valves are, as stated, slightly unbalanced so that there is a tendency for them to open. As soon as the pressure in the diaphragm chamber reaches thepredetermined point, the diaphragm actuates the lever 32 to close the valves.

If desired, a weight may be added to the lever 32 as indicated by dotted lines, to assist in opening the valves. The mechanism may be adapted for a vacuum control in which event the parts are reversed, the regulating diaphragm or regulating chamber being mounted on the bracket 22 or other side ofthe body and the connection being reversed.

The parts of my ,improved regulating njiechanismare such that they can be read-' ily assembled or disassembled for the purposes o'f r'epair. The; valve cage may be re moved without removing the body 1 from the line or system.

I have illustrated the body lasprovided with aremovable head at each end. In large structures, I contemplate making one head integral of having both heads removable, however, is of advantage in that the valve cage and valves can be removed f'om either end of the body as may be convenient.

I have illustrated and described my improvements in a simple and effective embodiment. I have not attempted to illustrate or describe various modifications which I contemplate as I believe thedisclosure made will enable those skilled in the 7 art to which this invention relates to adapt with the body.- The feature the same as conditions may require. I desire, however, to be understood as claiming my improvements specifically in the form illustrated as well as broadly within the scopeof the appended claims.
